Coordinating Research Council (CRC) Project E-55/59-1.5 had the objective of acquiring regulated emissions measurements from twelve in-use trucks in southern California, and supporting a third-party characterization of non-regulated species from five vehicles in the Phase 1.5 test fleet. In addition, three vehicles were re-flashed with a post consent decree engine map, and re-tested. One of the 're-flash' vehicles was also repaired and re-tested. A thirteenth vehicle was added to the study when difficulties were encountered in testing a new 2004 model year truck with intelligent traction control on the chassis dynamometer. The thirteenth vehicle was also a 2004 model year truck selected to satisfy the requirements for model year distribution of the test plan.
